包括铁道运输机车车辆发动机在内的各种装置的滑动轴承,都是采用巴氏合金、铅青铜、铝锡合金,有时也用锌基合金,但不多见。由于设备功率、圆周速度和工作温度逐年提高,因而对滑动轴承的要求也就随之提高。为满足这些要求,正在寻求依靠改变结构、改进生产工艺以及通过修正合金成份而 Including railroad locomotive engine, including a variety of devices, including sliding bearings, are used Babbitt, lead bronze, aluminum tin alloy, sometimes also used zinc-based alloy, but rare. As the equipment power, peripheral speed and operating temperature increased year by year, so the requirements of the sliding bearings will also be increased. In order to meet these requirements, we are seeking to change the structure, improve the production process and by modifying the alloy composition and
